One of the biggest attractions in Chile is the Atacama Desert. This expansive and arid region stretches 600 miles south from the Peruvian border and parts of the Atacama have not had any rain in over 300 years.
Visit the small adobe village of San Pedro de Atacama. The town square is home to one of the oldest churches in that area of the world. In addition, there is a small museum with archaeological finds.
One of the best trips in and around the Desert is to the Reserva Nacional Los Flamencos where the kaleidoscope of colors at sunset is spectacular. More information is here.
